On this adjusted basis, operating income in Fiscal Year 2012 increased 6.1% year-over-year. Excluding the special items noted in the attached financial charts in both periods, adjusted net income for the twelve months ended June 30, 2012 was $66.2 million, or $1.10 per diluted share, compared with adjusted net income of $56.9 million, or $0.95 per diluted share, in the comparable prior year twelve-month period. Using adjusted numbers in both periods, adjusted net income in the current fiscal year increased by 16.3% and adjusted earnings per diluted share increased by 15.8%.

Consolidated service revenue for Fiscal Year 2012 was $1,038.7 million in CRS, $167.1 million in PCMS, and $190.7 million in Perceptive.

The Company reported a Fiscal Year 2012 ending backlog of $4.394 billion, an increase of 27.6% over the ending backlog reported for Fiscal Year 2011. The reported backlog included gross new business wins in the quarter of $822.4 million, cancellations of $220.5 million, and a negative impact from foreign exchange rates of $39.0 million. The net book-to-bill ratio was 1.53 for the quarter, and was 1.76 for Fiscal Year 2012.

Mr. Josef H. von Rickenbach, PAREXEL's Chairman and Chief Executive Officer stated, "Fiscal Year 2012 was a watershed year for our industry, and a defining year for PAREXEL. We further solidified our leadership position in the marketplace as evidenced by an increase in backlog which grew 27.6% year-over-year, double digit revenue and earnings per share growth, and record high cash flow. Our differentiated product offerings have clearly resonated with clients, and we are a winner in a profoundly changed competitive landscape."

Mr. von Rickenbach continued, "After achieving a very healthy level of new business wins in 2011 and 2012, and accelerating revenue growth this past fiscal year, we will continue to be highly focused on client satisfaction and margin improvement going forward. We expect hiring needs to moderate over the course of the fiscal year, and to generate increasing productivity and efficiency from the more than 2,000 additional new employees who joined us during Fiscal Year 2012. Furthermore, we have a number of well-defined margin improvement initiatives underway which we believe will enable us to profitably convert our backlog and help us to deliver long-term sustainable growth in revenue and margins."

In separate press releases issued today, the Company also announced plans to initiate a $200 million stock buyback program, subject to the consent of the Company's existing lenders. In addition, the Company announced plans for the transition of PAREXEL's financial leadership.

The Company issued forward-looking guidance for the first quarter of Fiscal Year 2013 (ending September 30, 2012), and for Fiscal Year 2013. The Company expects to report consolidated service revenue for the first quarter (ending September 30, 2012) in the range of $395 to $400 million and GAAP earnings per diluted share in the range of $0.28 to $0.30. For Fiscal Year 2013,consolidated service revenue is expected to be in the range of $1.630 to $1.660 billion and GAAP earnings per diluted share in the range of $1.33 to $1.45. (Previously issued guidance for Fiscal Year 2013 was for service revenue of $1.625 to $1.655 billion and GAAP earnings per diluted share of $1.31 to $1.47). The guidance does not include any impact from the Company's recently announced stock repurchase program.

In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), the Company uses certain non-GAAP financial measures. The Company believes that presenting the non-GAAP financial measures contained in this press release assists investors and others in gaining a better understanding of its core operating results and future prospects, especially when comparing such results to previous periods or forecasted guidance, because such measures exclude items that are outside of the Company's normal operations and/or, in certain cases, are difficult to forecast accurately for future periods. Management uses non-GAAP financial measures, in addition to the measures prepared in accordance with GAAP, as the basis for measuring the Company's core operating performance and comparing such performance to that of prior periods and to the performance of its competitors for the same reasons stated above. Such measures are also used by management in its financial and operating decision-making. Non-GAAP financial measures are not meant to be considered superior to or a substitute for the Company's results of operations prepared in accordance with GAAP.
